Cincom Open Sources 'Frost'

To my (admittedly biased by what I work on) mind there are two big things I 
think we could get out of Frost relatively easily, and neither of them 
requires dealing with the messy GUI stuff.

First, JDBC drivers. Squeak, and Smalltalk in general, could instantly gain 
drivers for all major databases, many of them using socket connections 
directly. In some cases it would be impossible to write that code directly 
in Smalltalk because the database vendors don't publish the protocol, but 
it's embedded in the driver.

Second, JSP. While the basic syntax of JSPs is quite simple, authors have 
the ability to embed fairly arbitrary Java code into the pages, so it's not 
easy to write a Smalltalk system that can run existing JSPs that include 
code. While the code is arbitrary, it's usually not all that complicated, 
consisting of calls to domain objects and to databases plus maybe some RMI. 
Using Frost this wouldn't require a whole lot of primitives.

Obviously there are a lot more things we could do, but these seem like two 
that are relatively easy pickings.
