A couple of suggestions from someone who has done that over 5 years.
* Do *have* a mailing list. Nothing beats it reach.
* Have a good ticketing system. We used to let people who are online to pick up tickets from any geo and work on it unless it is something that requires hands on , in which case, we used to pass it on to the local contact.
* Use a good text based chatting solution. Video / audio solutions are good, but text is better for a lot of things, like small talk , sharing links or a way to avoid misunderstanding or misinterpretation that could happen in speaking. I generally prefer IRC for group chat. Setup a proxy server for IRC like https://code.google.com/p/dircproxy/ or have some form of logging and you could let users catch up with whatever happened on the channel while they are away.
* Arrange their timings, such that atleast one person from each geo will have atleast a hours overlap with a person from the geo closest to him. EG:
* Have video meetings r meetings over the phone atleast once a week.
* Get them to put their pictures, phone nos., and responsibilities on a intranet / address book.
* Have weekly meetings in any medium and if you can't have everyone to have their say, let one person from each geo each week talk about any issues they have or something good they did that week.
* Other collaborative software that is good to have : wiki , version control, Calendar (egroupware / google / exchange) , pastebin (share code / error snippets).

I think it has its uses as a replacement for Dynamic fonts. Dynamic fonts was mostly useful for Indic and other complex scripts at a time when Unicode was still nascent and there were still challenges in getting Indic and other scripts rendered properly. Publishing houses (all of them earlier and most of them now) use an ASCII based font and push dynamic fonts to IE users while expecting other browser users to download them. While Unicode should make this moot, slow adaption of Unicode by publishers and users and the fact that by default, most Windows XP installs did not come with Indic pre-configured means there is still market for this hack. Publishers could push either their ASCII hack font or Unicode font to users this way at least until there is more mainstream adoption of Unicode and in the process help non-technical people, especially those not using IE, access to content with less issues.

Another effective and greener solution is to use Turmeric. It does not kill ants, but just deters them.
