Screen Sharing Plugin for Pidgin

[Ashish Vijaywargiya]

Yesterday I was chating with my friend who was using Mac Book Pro and
I am using Ubuntu 8.04.

He was using iChat and I was using Pidgin for IM purpose.
In our conversation he asked to share his screen with me as in iChat
they are having option to share the desktop but it was disabled for me
as I was on Pidgin.

Do we have some plugin to enable the screen sharing in Pidgin so that
we could do screen sharing with the person using Mac ?
Any other interesting software that works with iChat screen sharing option ?

Thanks in advance for any response.
