You bet.  We would be thrilled to have you work on compiler warnings, 
and on attribute parsing (which is related).  This is an area that is 
purely in Java, and makes a huge difference to people's first 
experience with the product, and therefore to its adoption.  It's also 
an area that we badly need help with.

Here's a problem that came up recently.  The following program:
   <canvas>
     <view width=" ${50}" height="50" bgcolor="red"/>
   </canvas>
gets a cryptic compilation error:
   test.lzx:2:53: Syntax error: the token "{" was not expected at this 
position.
It also gets a terrible compilation warning:
   test.lzx:2:51: The value of the 'width' attribute uses a deprecated 
syntax. Use width="${ ${50}}" instead.

The program is fine, it's just that there's a space before the "${" in 
width=" ${50}".

The problem is in the way NodeCompiler.compileAttribute, in 
WEB-INF/lps/server/src/com/laszlosystems/compiler/NodeCompiler.java, 
parses the attribute.  It should use a regular expression instead of 
string.startsWith().  I think the regular expression is something like 
"\s*$\s*(immediately|once|always)?\s*\{(.*)\}\s*".

Would you be interested in looking at this?
