Rockon!

Strange, this should be right in CVS.

The plugins are completely thread safe, it's a requirement
in plugin design but libvisual will support
VISUAL_PLUGIN_FLAG_NOTRENTRANT flag in the future.

Ofcourse the case is different for GL plugins but that won't work in
your setup anyway :)

Libvisual handles size issues transparantly, using the VisActor you can

if conflicts arise :) So you're safe here as well.

We are deadly serious.

Nah, seriously, I for instance has never been as motivated (and for such
a length of time) about working on a project as the case is with 
libvisual. We will get the job done.
