What Notable Differences are there between Railo, Open Bluedragon, and Adobe Coldfusion?

An attempt to capture notable differences between implementations:

  1. Adobe ColdFusion
  2. Railo
  3. Open Bluedragon

(I'm aware of Smith, but don't believe it's still active).

Include CFML and platform differences - syntax, feature, and extensibility.

Note, this is not something I've not seen anywhere else, but maybe I'm just not searching correctly. So links to that end would count too.

Update

Here's my definition of notable in this context: something that simplifies solving a difficult problem. For example, Railo offers the <cfvideo> tag, which transcodes video - a non trivial task.

Something I would suggest is not notable: the Railo function ListAvg().

    Overview

    Aggregation of items I've called "notable":

    Open Bluedragon

    1. Web based line debugger: Adobe Eclipse based is finicky.
    2. Memcached intregration: Adobe ehcache solution works well, but memcached still appears to have better failover and sharding. In fact, sharding appears to only be available in Adobe with Terracotta or rolling your own.
    3. Runs on Google App Engine

    Railo

    1. <cfvideo>: video transcoding, pay feature, but low cost, free option is ffmpeg, but that has legal question marks
    2. cluster scope: interesting way of solving messaging between servers, pay feature.
