Do you have any plans to update the pidgin build to a newer version? The pidgin version you posted runs a lot smoother than the X11 version, however it does not support the sipe plugins to connect to lcs or lync servers...
I don't have any plans. I'm busy with other projects. I'm not sure I will ever have the time on this again as I'm currently using other software (Adium).
Feel free to provide patches!
