When we    accept such limited o/h funds we cost share from corporate
funds..for exactly the reason you state...we cannot push the burden of o/h
disproportionately to fed funded projects by relieving other projects of
the negotiated rate...we have had a few other situations with non federal
client where we have presented costs in a way to recover some 0/h..with the
stated caveat that our accounting system may not track costs in the exact
manner of the presentation...that is kind of squishy but with some less
restricted clients is possible
