Dotcomformat

Hello all...

I'm currently researching my first modular set up. Originally it was 
going to be Euro Rack format but after looking around I'm not so 
sure. The Dotcom entry system is very appealing as starting point but 
I can see myself wanting to branch off

- My first question is, how difficult is it to integrate Modcan (B 
Series) modules into a dotcom set up, using the .com power supply? 

- I'm planning on using the rack frames to mount my .com modules into 
a rack system. From what I understand the .com rack frame would need 
to drilled in order to screw in Modcan B series modules, are MOTM 
rack rails directly compatible with Modcan modules or would I have to 
drill those as well? 

- I figure incorporating MOTM modules should be as easy as using 
their rack rails and one of these:

or some of these :

Is that correct or is there more involved? 

Thnaks for any help with this.
