Yeah, that's a tough one. The track functionality is pretty limited. While we have all sorts of features and improvements planned for track, providing what amounts to single character search or regular expression search isn't really possible at the current product of tps and client cardinality. If this $ thing really takes off, we might be able to make some special case for it, but such a feature isn't likely in the near future.
Describe your application, how data is consumed and displayed to a...@twitter.com, and perhaps we can grant elevated access to 10,000 items. I'd guess 10k should cover most of the non-OTC US equity markets or the vast majority of global equity by market cap. 26^4 is only a half million. -John Kalucki http://twitter.com/jkalucki Services, Twitter Inc.
