Domain Test is a tool that we made to help with this. It's accessible at http://domaintest.foo and on ~120 other TLDs (including some IDNs).
It's similar to what you propose, except that it by design can only work with valid domain names. (For obvious reasons, we can't have an invalid TLD point to a hosted test suite.)
Check out the documentation link from the page above to learn how it works and what domains are compatible with it.

Some people may be happy to register their own domain name for each of the categories - but not everyone might. Particularly for the Unicode.unicode.I’m wondering if people have any ideas of how we might be able to create a public resource that people can use to test their systems if they don’t want to secure their own domain names? One thought had been to set up a mailing list that is publicly visible and people can access that to see if their welcome message appears.I would very much welcome those of you with a Geeky bent to let me know (on or off list) of any ideas the you think might work.Thanks.Don
