Testing a few on W7-64 bit, client 6.10.19 and noticed that a result in the quorum was listed without the version number, only 2 returned to date:

my507_ 00020_ 3-- - Pending Validation 29-11-09 09:06:10 29-11-09 18:45:23 4.82 53.2 / 0.0 < no version
my507_ 00020_ 9-- 603 Pending Validation 29-11-09 09:31:15 29-11-09 14:39:48 4.50 82.9 / 0.0 < mine

The message log does not say what platform this task was processed on, a nice, none privacy invading feature this would be since HPF2 and RICE are mixed platform quorums.

Result Name: my507_ 00020_ 3--
<core_client_version>6.6.36</core_client_version>

A quick search does not reveal this having been reported before on HPF2.
