Idealized speaker community

An idealized speaker community is a concept proposed by Noam Chomsky, which argues that to understand a language, linguists must assume a perfectly homogeneous speech community. So we've proposed co-opting the phrase as a new form of conlanging (linguistic construction), in which idiolect leveling a heterogeneous speech community. Here's the email Arthur sent, more to follow. Hey folks, at our first meeting, we talked about creating our own language. For some reason, after our screening of /The Linguists/ tonight, I had a brainstorm related to that. How would you guys feel if, rather than try to create a language as linguistically unusual as possible, we tried to create a language by speaking it? Here's my thoughts on how this would work: We'd do it like an ESOL class, one person would present a lesson, and then people would practice in small groups. The lesson would be entirely in the language. Initially, the learners would naturally simplify things that we don't find useful, later, as we get better, we can dispense with the grammar lessons, and innovate new forms, some of which may stick if the speakers find it useful. The idioms and compounds that we develop might also be interesting. (Conlangers tend to either calque from their own language, or go to the other extreme, and do things that make no sense.) We will agree on no formal rules about phonology and grammar at first, but we should undoubtedly see patterns develop like a linguistic Ouija game. How's that (or some variation) sound to you guys?
