I see well I wouldnt really consider that as proper file transfer, its 
more just sending a link to someone, also just had a look at the 
documentation for pyMSNt and that says it already supports MSN 
filetransfers using SI (XEP-0096,XEP-0065) so this argument is pretty 
much moot as its already been implemented in one of the more widely used 
MSN transports, also it really is not that difficult to implement and 
the reverse engineered protocol docs are out there, the protocol for 
filetransfers on msn also doesn't change (at all AFAIK) for a particular 
version of the MSN protocol (microsoft versions their protocol with 
official clients and servers supporting several versions, when you 
connect you tell the server which version you wish to use), I would 
suggest you read up on the MSN protocol to better understand things.

So in conclusion its already been implemented (so not the issue you are 
trying to make it out to be), there is no need to worry about the msn 
protocol side suddenly changing as it simply won't unless the transport 
is upgraded to support a newer version of the protocol in which case the 
developer will know that they will need to make modifications to the 
protocol handling.
