OK, thanks, I'll take a closer look at the PUD plugin code. One thing I
did not understand from the pud.odt plugin description document is the
overview part, which seems more concerned in the scenario where the OLSR
network is used to transfer GPS updates between networks, rather than
the simpler case of internal GPS update distribution.
At any case, the PUD plugin is a 'push' type mechanism, where updates
are constantly distributed whereas the suggested solution is a 'pull'
type mechanism, where updates are only maintained but not distributed,
until a request for them is made.
I'll cleanup the implementation I have to hopefully include it in 0.6.3.
