I would like to request that the Skype Android client implement instant messaging URI receivers for the "im" and "imto" schemes. The default Android dialer application attempts to use instant messaging URIs to start chats with supporting applications. For example, the Skype URI it uses is "imto://skype/[username]". Others include "imto://gtalk/[email]", "imto://aim/[username]", etc. Replace the values in brackets  with the corresponding username or email address of course. As it is now, when a user clicks the chat action for Skype on the default dialer, nothing happens at all (not event a toast message letting the user know that nothing is happening, how disappointing). See below for supporting links and information.
Starting at line 187, the default Android contact application attempting to invoke a chat.
The Wikipedia entry for Uniform Resource Identifier (URI).
The Wikipedia entry for URI Schemes, the official instant messaging scheme is "im" however Android uses "imto" (hence my request for both "im" and "imto" receivers).
