Thanks to Kit Baum, -psmatch2- is available from ssc.

Main features are faster 1-to-1 matching, full mahalanobis matching and saving 
of the overall weight of the matches.

For those interested more stuff is listed below.

Enjoy, Ed.

* general
  - allows multiple outcome variables
  - generates weights for all matching methods
  - more sophisticated common support trimming
  - pstest and psgraph utilities, to test covariate balancing 
    and common support
  - apart from the average treatment effect on the treated, it optionally
    calculates the average treatment effect on the untreated, and 
    the average treatment effect

* nearest neighbor
  - faster
  - allows matching with and without replacement

* mahalanobis
  - full mahalanobis (f.e. psmatch allows max 3 vars)

* kernel & llr
  - can match both on propensity score and mahalanobis metric
