In Stata Version 9, it is possible to use the svy command with balance
repeated replication (BRR) weights in the case of privacy-conscious data
sets. i.e. data sets which do not provide variables that identify the PSUs
and strata, but instead provide, for example, bootstrap weights that can be
used to estimate the appropriate standard errors.

In previous versions of Stata this type of analysis was possible with the
BSWREG ado file.

However, there are data sets in which the bootstrap weights provided are
actually *mean* bootstrap weights. For example, 500 bootstrap weights may
be provided, but each one is the mean of 12 weights (i.e. there were
originally 6000 bootstrap weights created, but only 500 are provided). The
BSWREG command is able to take mean bootstrap weights into account with the
cmeansb option.

Does anybody know if it is possible consider *mean* bootstrap weights with
the svy command in Stata 9?

(not taking the fact that they are mean bootstrap weights into
consideration results in SE estimates that are biased downwards)
