I received this heads-up from Microsoft today:

The Live Mesh team is expanding the list of countries that will allow sign-up without a wait list to include Canada, India and Ireland .  As Live Mesh heads towards a more open beta later this year, the team continues to increase the number of participants.  This expansion is in addition to the availability previously announced for the US, UK, Australia and New Zealand customers.

Here's the blog post:

Today we are again increasing the number of available slots in the Live Mesh Technology Preview, and expanding the list of countries that will allow sign-up without a wait list to include Canada, India and Ireland! (although you still need to run with an English locale for now.) This is in addition to the availability we’ve previously announced for USA, UK, Australia and New Zealand (see coverage map).

We do still have a maximum limit on the number of users we’ll allow into the Technology Preview, but as long as we’re below the limit, anyone in the countries above can sign-up today with no delays or wait list.

Come to the Mesh. :) You know you want to.
