at least one cloud storage location and at least one network or local storage location.

10. The computer storage media of claim 1 , wherein the proxy is configured to cast at least a portion of the user interface content to a display device or to another web application.

11. The computer storage media of claim 1 , wherein the proxy is configured to dynamically establish a peer-to-peer VPN session.

12. A method for providing a secure software client, the method comprising:

providing a proxy that executes as a native application on a computing device of a user;

providing a web application that executes within a browser on the computing device of the user, the web application being configured to communicate with the proxy via a communication channel;

generating, by the proxy, user interface content defining a desktop that includes multiple representations of respective-multiple applications that the proxy determines the user is allowed to access, the multiple applications including at least one remotely hosted application and at least one local application that is hosted on the computing device, wherein the representation for each of the at least one remotely hosted application includes connection information for the remotely hosted application, wherein the user interface content further includes a representation of content to which the user has access and wherein the user interface content is HTML 5 content;

receiving, at the web application, the user interface content defining the desktop;

rendering, by the web application and within the browser, the user interface content to cause the desktop to be displayed in the browser such that the multiple representations of the respective multiple applications and the representation of the content to which the user has access are displayed to the user as part of the desktop;

detecting, by the web application, first user input to the desktop displayed in the browser, the first user input selecting a first representation of the multiple representations;

sending, by the web application and to the proxy via the communication channel, one or more communications that identify a location of the first user input within the desktop;

determining, by the proxy, that the location is associated with the first representation of the multiple representations, the first representation being associated with a first application of the multiple applications, the first application being a local application;

based on the determination, invoking the first application on the computing device,

detecting, by the web application, second user input to the desktop displayed in the browser, the second user input selecting a second representation of the multiple representations, the second representation being associated with a second application of the multiple applications, the second application being a remotely hosted application;

in response to the second user input launching, by the web application, a separate browser window which uses the connection information included in the second representation to display a user interface of the second application within the separate browser window;

detecting, by the web application, third user input to the desktop displayed in the browser, the third user input selecting the representation of the content to which the user has access;

sending, by the web application and to the proxy via the communication channel, one or more second communications indicating that the representation of the content to which the user has access was selected;

in response to receiving the one or more second communications, generating, by the proxy, additional user interface content that includes a representation of one or more files or folders included in the content to which the user has access and sending the additional user interface content to the web application via the communication channel; and
