Possible to install APK from personal website? How can I allow a user to do web-install of Android APK file from my personal web page? Like to create a personal (private) APK repository where I could put APK files and send a client the link to the APK file. A client would then click on this file and install the Android app to its phone. 

Is this possible/allowed on the first place?

Any cool tool a user should use for installing such apps?
Once the user allows Unknown Sources, they should pretty much be able to get APK from anywhere...
