My team has been using Ext with DWR for almost year a year, and have had nothing but good things to say. If you take this approach, you will end up using DWR's generated JavaScript classes for making your requests to the server. This will often be done in place of using the Ext.Ajax and Ext.data.Connection classes. ... |

On larger and/or long running projects, I tend to reference many assemblies and namespaces, and often I end up removing some functionality later on or moving it into a different project.

[Get Types][1] gives you a list of [Type][2] objects defined in the assembly. That object has a namespace property. Remember that an assembly can have multiple namespaces.

Firewall is always possible, but it does say that ssh can connect, so that seems unlikely.

You can't perform short-circuiting of function call arguments using a regular function call. For example:
#define andm(a, b) (a) && (b)
bool andf(bool a, bool b) { return a && b; }
andm(x, y) // short circuits the operator so if a is false, b would not be evaluated
andf(a, b) // b will always ... |

<tt>$0</tt> is typically the name of your program, so how about this?
use Cwd 'abs_path';

Seems to me that this should work as <tt>abs_path</tt> knows if you are using a relative or absolute path. |

The only way I see the two interacting would be to place both a WMP and a Flash component on a web page, then have JavaScript to manipulate the two.
