Thanks to Kit Baum I have posted the following package on SSC:
TITLE
'SSI': module to estimate sample size/power for randomized controlled trials
DESCRIPTION/AUTHOR(S)
ssi is meant to be used by investigators needing sample size/power
estimation for prospective randomized controlled trials (RCTs).
Although Stata ships with a sample size estimation command,
sampsi, it is not designed to estimate trial sizes for
non-inferiority or equivalence trials.
KW: sample size
KW: randomized controlled trials
KW: sampsi
Requires: Stata version 11
Distribution-Date: 20100517
Author: Philip M Jones, University of Western Ontario
Support: email [email protected]
INSTALLATION FILES (type net install ssi)

Full usage instructions are given in a detailed help file that accompanies the package. Please e-mail me with any suggestions for improvements or changes.
Kind regards,
Phil
