They are all on SqueakMap and/or SqueakSource, here are some links :
- rST : http://minnow.cc.gatech.edu/squeak/2288
- RMT : http://map1.squeakfoundation.org/sm/package/94bba4b0-3b56-4af7-8a6e-5c4bb6a55e36
- OperaORB-native (based on RMT) : http://map1.squeakfoundation.org/sm/package/b6fd0af9-5f51-4755-b647-6df64682e192 and http://www.mars.dti.ne.jp/~umejava/smalltalk/soapOpera/operaORB.html
- Ma Client Server : http://minnow.cc.gatech.edu/squeak/2978

If you are looking into paralellizing the image for distributed development you should be interesting in Magma (http://minnow.cc.gatech.edu/squeak/2665), which is basically a multi-user object database, but can serve (with Monticello) as a basis for distributed development (http://minnow.cc.gatech.edu/squeak/5602).
