I have a similar situation . . . . . but not with "Mobile Clients" . . . . . 
I wrote the below setup before I realized your config does not locally 
define what IPs are sent over the connection . . . . . you may be able to 
set up the remotes with 2 mobile tunnels each to the corporate LAN . . .

Do all 3 locations have Monowalls?

Monowall currently can only send one subnet over one IPSEC connection (I 
think) . . . . . .

you have to add IPSEC tunnels to each remote using the other remote's 
Remote1 IPSEC on the corporate Monowall has 2 tunnels:
Remote2 IPSEC on the corporate Monowall has 2 tunnels:

I have a client with 3 locations using #1 as the endpoint for #2 & 3, in 
order for 3 to talk to 2 I had to set up separate tunnels for each IP range 
. . . it took me a little thinking to understand how this works and 
configure it.  (currently I have 10+ tunnels running between the above 3 
locations to route all the traffic).

One of the outside vendors connecting to my client using CISCO mentioned 
that he's never seen someone get the routing between other VPN tunnels 
working so fast and easy, kudo's to Monowall for that!
