Is RSB in a self contained desktop application viable

[everettmuniz]

It looks like the service bus concept is more typically applied to
distributed scenarios. I'm extremely new to the service bus world but
I was recently asking around on the NHibernate list about the best
approach to developing a multi screen desktop app where you might
have several screens open and want each to have it's own session
(http://groups.google.com/group/nhusers/browse_thread/thread/
706451ca38599b4d?hl=en) There's some work that has been done in the
unhaddins project to address this scenario but someone else suggested
considering tackling the problem with a service bus.

I've been looking at RSB and it's provoked a couple of questions:
(1) our project is a totally self contained desktop app, is a service
bus considered a reasonable solution in that context
(2) our product will be a commercial application that users will
download and expect to install easily -- is there anything about that
scenario that would rule out RSB?

You can certainly do that.
You can use RSB + RQ to have a zero install footprint.
Although you probably want to patch RQ so it wouldn't go over the network to pass messages around.

thanks for the response Oren!  

I feel like I'm asking inane questions so I apologize if that's the case.  architecturally, i'm really attracted to what's appears to be possible in the service bus scenario but I'm really green on the concept and even more so on the tools and how to use them.  I'm feeling my way here - these are questions out of genuine ignorance.  

i gather RSB + RQ means combing the Service Bus with Queue project.  why would I need to combine the 2 projects?  

also, when you say "zero install footprint" could you unpack that a bit.  are you saying that the core RSB assemblies with relevant referenced assemblies would be all that the install would need to include.  i wouldn't need to do anything relative to msmq?

is there a reference app anywhere that shows what using RSB in this context might look like?

[Ayende Rahien]

RQ means that you don't need anything installed on the client, but you get persistent queues support.
If you don't care about persistent queues, you can implement an in memory transport.

RSB provides the bus, it relies on an underlying queue impl.
Currently we support both MSMQ and RQ

Zero admin means that you don't need to install a service, setup queues, etc. It is just running in your app.

Ok, excellent, many thanks.  I'm going see if I can spike something simple and go from there.
