Do you have a likely date for the availability of the new release (other than RSN)?

Lady Heather has support for setting the system clock from the GPS receiver.  The next release has support for analyzing and compensating for the GPS / system / com port message delay.  It does not use the 1PPS signal.   

It can get the Windoze clock to under 40 msecs (two times the typical Windoze 16 msec clock interval).   It can reset the system clock on command, periodically, or whenever the GPS time and system time diverge by more than x milliseconds.  However it does not have the finesse of NTP that guarantees on monotonically increasing system clock... it just "jam syncs" the clock to the GPS time.  I know there are people using it for EME work in the field where there is no net connection available for NTP, etc.   

Plus the next release can give you the moon az/el/phase/age/ rise+transit+set times and draw a pretty picture of the moon at its current az/el and give you your location in Maidenhead, UTM, NATO, etc coordinates.
