Volume has been a real problem. Usenet is probably close to 10MB/hour
these days, which is 30 kbps if you don't compress it, or 10-15 kbps
compressed (since the binary newsgroups are a good chunk of the volume
and are already mostly compressed.) That's pushing what you can do with
really-low-end satellites, and as Tim says, the Web has affected the
size of the market for that kind of service.
I don't know how easy it is to get one of these pseudonymously, and they
do cost a bit, but an amusing transmission medium for message pools is
alphanumeric pagers; you can get pager cards for PCs, or just limit
your messages to 250-byte blocks.... Bay Area alphanumeric service
probably costs $25/month, though nationwide is $60-100.

Getting everybody is tough. Getting a lot of the potential suspects,
however, isn't as tough as it looks - the vast majority of home Internet
users are on AOL, Compuserve, Prodigy, UUNet, Netcom, or (RSN) AT&T.
Anonymous Message Pool users are a bit more likely to use niche-market ISPs,
especially under pseudonyms, but if the number of users increases
significantly there'll still be a reasonable proportion on the big carriers,
which are probably more cooperative and probably keep more complete logs.
On the other hand, several of the big players are good places to get
disposable accounts charged to that secured Visa debit card you
opened under a pseudonym....
