[Twisted-Python] TOC and filetranser

[achin]

hi, I'm writing an AIM bot using twisted's TOC implementation.  i was 
wondering if this module supports file transfers (namely sending from the 
TOC client).  and if so, could i get either some sample code, or a more 
detailed documentation than the one at twistedmatrix.com

my first question regarding the SendFileTransfer class is what exactly is 
the "cookie" parameter in the __init__ method? (i don't see it documented 
anywhere)

as a side note, i was wondering if a TOC2 python module exists, as i think 
TOC2 would be preferable over TOC

thanks,
