John,
   Hayes has recently announced December availability of the ACCURA ISDN
product.  Here's some info:
 Now telecommuters and Internet surfers can reach a maximum throughput of 460 
Kbps. ACCURA
ISDN is one of the fastest ISDN terminal adapters on the market - four times 
the speed of
V.34 analog modems and two times the speed promised by 56 Kbps modems.
ACCURA ISDN supports up to six external analog devices for sending data, fax 
or voice
transmissions off a single ISDN line so reduration utility for easy, one-time 
installation
and set-up.
For ALL of the specs, you might want to see our web page at:
http://www.hayes.com/isdn/accurai.htm
It doesn't have a V.34 modem built in, but comes with 2 POTS ports so
you can connect whatever analog devices you like.
With internal ISDN devices you have the advantage of having the high
speed port taken care of, but I always prefer externals.  With externals
you have the advantage of portability, between specific machines,
machine types and operating systems.  With internals you are dependent
on specific software drivers.  The ACCURA ISDN will be introduced as an
external only.  The Hayes ESP supports throughputs up to 921,600 bit/s.
Using SIO under OS/2, I believe you can achieve 230,400 bit/s
throughput. (In fact, with the ESP I believe SIO will accept up to the
max. of 921,600 bit/s as a valid rate).
