Both :)

You could deploy multiple spring applications / deployment units inside 
a single Geronimo container & hot swap them along with any other J2EE 
deployment unit (WAR, EAR, RAR or new ones like CARs or SARs). What 
with all the management stack & tools, I'm thinking it might be a neat 
idea for folks to develop in Spring (nice & simple, invisible 
lightweight container etc) then when they get into production, when 
their pointy haired bosses insist on running everything in standard 
configuration J2EE app servers, we just drop in the spring deployment 
units.

i.e. allow Spring to have its own deployment unit for running stuff 
rather than having to stick with EARs or WARs. Of course EARs & WARs 
are supported too - this just allows an extra option - treating Spring 
as a peer of WARs and EARs inside Geronimo.

i.e. having a custom transaction manager plugin for Spring which can 
take advantage of all the features available in Geronimo's transaction 
manager.
