Fasp versus FTP

Why on earth would anyone buy a data transfer protocol, especially one where the developers feel they need to put "TM" on every instance of its name?

Anyone remember the history of Zmodem? The wikipedia article doesn't mention it, but there were fewer implementations for fewer OSes than could have been, due to weird-beard legalistic threats. How would "faspTM" be any different?

Besides that, "fasping" sounds like some bad Sci-Fi euphemism for "shining the shaft".
