Lots of vendors have really crappy install routines that replace the 
most recent, downwardly compatible versions of some DLL with the 
version they developed with that of course isn't upwardly compatible.  
Prime example: Installing Orcad 9.2 will kill the MSDN help viewer 
because Orcad overwrites mshtml.ocx without bothering to check whether 
or not the version already there is newer.

Hmm... do they start out at a "least common denominator" setting (a lot 
bit rate) and then shift upward when both "parties" (the car and the 
PC) have verified that they can handle it?  I'm trying to think of what 
someone would choose to implement such a "feature."
