Hate to burst the bubble of those who think Swype is about to be available for purchase in the Market after a short "beta" period; that's very unlikely. Swype has not changed their strategy of marketing to OEM manufacturers. They've simply made a version of their keyboard available to a select group of users on the Android platform to test its functionality and performance.
As the folks at Swype have said repeatedly, they are not staffed to provide support to thousands (much less millions) of individual users. Furthermore, they want to be sure their product works identically in every device. With the Android platform proliferating to a wide variety of devices, that is a daunting challenge. Finally, if you were a software firm and had a choice of receiving $2 on every one of 100,000 devices sold or $5 for 20% of 100,000 devices which would you choose?
If you don't know the answer to the last question, you shoulda paid more attention in the fifth grade.
