TK; Yes this all makes sense, and is as you state it. There is a tradeoff between server-side (backend inferencing) and client-side inferencing. Server-side support for inferencing is thus far is quite limited.
Any way you look at it, it's a matter of memory usage. You can either load your server with memory - AllegroGraph, Oracle 11G, Sesame, etc. will run as poorly with inadequate memory as any client software - or load a local machine with memory. Thus the real tradeoff comes down to where you have adequate memory to run the queries/rules/inferences you need. These are some of the issues we are working to address in TopBraid Live, our semantic application server. Also, in terms of OWL support, I'd suggest taking a look at the recent OWL profiles work (http://www.w3.org/TR/2008/WD-owl2- profiles-20081202/). Holger's blog is also informative on the issues facing OWL and the rise of different modeling paradigms (http:// composing-the-semantic-web.blogspot.com/2009/01/object-oriented- semantic-web-with-spin.html).
