Not neccessary. You just can stay online in transport but offline in jabber. 
In this case all your proprietary network users will see you as 
"online" (probably some sort of xa is better idea) and send you messages that 
will be queueed in server. So you will not need any hacks in this case. You 
will just need to not subscribe your transport to your presence so when you 
will go offline in jabber - transport will not notice it and will stay 
online.

If proprietary network doesn't support this then this should be done either in 
transport (how to do it depends on transport that you use) or in server (to 
store messages for remote clients).
