Be aware that if you do a search on the product, it is called
"S+SeqTrial". The Insightful page for it is at
http://www.insightful.com/products/seqtrial/default.asp

Also, FWIW, there is another book that you might want to look at, simply
as an alternative resource:

http://www.amazon.com/exec/obidos/tg/detail/-/0849303168/
Group Sequential Methods with Applications to Clinical Trials
by Christopher Jennison, Bruce W. Turnbull
CRC Press; (September 15, 1999)
ISBN: 0849303168

Others here may have other references that would also be helpful.

HTH,
