Hi Dirk and others.

I would like to replace the PC41 protocol for CC Clusters.  Dirk, some
time ago I remember you mentioning you were looking into replacing PC41s
as well.  I have heard nothing recently.  If you have a design for your
protocol, I would like to see it.  Perhaps I could use it.  Otherwise,
what I am proposing to do is introduce a PC91 message, similar to the
existing PC92/PC93 messages.  Will this cause anyone a problem?  If not
a PC91, then any suggestions to another message number?  If Spider sees
this message, could it at as a minimum decrement the hops and pass it on
to other Spider clusters as well as CC Clusters?   

This message would include all the data currently passed in PC41s and be
expandable to include other items if desired.  ie IOTA number, RDA etc.

The format I plan to use would be of the type

PC91^VE7CC-1^65205.01^version^VA6AAA^1^Lee^2^Maple Ridge BC^3^49 11 N
122 30 W^4^VE7CC-1^5^CN89^H99^

These items are ^orig node^time^PC91 protocol version^user call^item 1
of PC41^item 1 data^item 2 of PC41^item 2 data^... up to item 5 data of
PC41 and then additional items not currently included in the PC41
protocol.   

It would be optional how many items of data are passed in one message. 
A minimum of one and a maximum of all items.  Each item type (name,
location etc) would be identified by the number immediately proceeding
it. 

Comments?
