Dave,
I don't work for TF, but from the results of the response to Garmins Logbook, I can pretty much gurantee you that they won't be supporting TC either.
Garmin as of late has started to take on this whole privacy and not wanting to share data with outside developers. SO with these proprietary formats of xml and hst, Garnmin is locking you into their software, or some of the programs that people are writing on their own.
For the commercial deverlopers, it ain't worth their time to try and decipher the crud. Not till Garmin monopilizes the market.
I do use a FR201, and as noted above, I download each run after copmpletion and get the track. If I can't download on that schedule, as say I'm on a multi-0day trip wothout pc access, I don't reset till after the trip is over, then download the one big run and manually break it into the indvivual runs. While I might lose some data, it's better then limiting my runs to the 250 point format they created.
Least, my 2 pence.
TC
