We use PC Pursuit at seismo. It works. It saves us OVER $1500 per month
in long distance charges. We have used it since October, 1985 with no real
problems.

There are three drawbacks. 
	1) The throughput with "normal" unix uucp 'g' protocol is bad.
		You get about 600 bps on a 1200 baud connection.
		However, the cost is not dependant on time, so it is reasonable
		to use. They are supposedly installing 2400 baud modems.
		This will help.
	2) Some cities are hard to get to. Because they have been 
		agressiveley pushing this service, the demand has far
		outstripped the capacity of the service in some cities
		(Especially San Francsico and Chicago. Boston isn't great
		either). They claim to be monitoring traffic and adding
		capacity. I haven't noticed any improvement. (Then again,
		demand may be increasing as fast as they add service so it
		may just not be getting worse).
	3) For interactive (i.e. human) use its not too great. The character
		delay inherent with telenet/tymnet/etc is quite apparent and
		annoying if you are a decent typist. For browsing a 
		b-board its probably ok. For using a screen editor is sucks.

However, for data transmission I think it is a big win and people should look
into it.

We send over 170 megabytes of electronic mail per month  through PC Pusuit
and will keep doing it.
