Live messenger and ISP thorttling?

I'm beginning to worry about the bandwidth demands of Live Messenger of late. 
 It appears that some ISPs are starting to thorttle ANY type of p2p 
connection, including Live messenger.  Does anyone working on development 
perhaps know if there is a workaround, pending fix, or add in to messenger 
that could do things like adjust the threshold of bandwidth used to keep the 
video chat function from being squeezed by the ISP, or some way to at least 
adjust the audio quality manually so the dropouts will be minimal if this 
happens?  either that or if the bandwidth is being restricted, back down on 
the video framerate, THEN the audio quality?  this shouldn't be an issue, but 
has been seen as a problem more common of late.  A simple 'power tool' type 
of add in should be available?   Or is there an SDK that can be downloaded
