“Proper” retweet method is still misunderstood – help!

I’ve been trying to hack together some code to carry out proper retweets for a while, and I’m kinda stuck.  So I’m posting this as a request for some help, has anyone cracked this?

Whats the problem?

In the beginning a retweet on twitter was considered to be any tweet with “RT @hamlesh” in the tweet.  However a proper retweet (I don’t know what else to call it) is one using the twitter retweet function (which not all apps have – still)

The following tweet should demonstrate what I am talking about.

You can see, these were retweeted “properly” – using the retweet button/method.

Now the following tweet by JasonJGale

Was retweeted by BeckySocial, using whats now dubbed the “mention” tweet functionality, as there are no “Retweeted by…” statistics.

Now what I want to know, how the heck do we trigger proper retweets so that the relevant META data is preserved – and furthermore is this possible through the open RSS feed data?  Simply affixing RT infront of a tweet is no longer enough.

Can anyone help? — @hamlesh on twitter if you’ve found a solution or can offer any guidance.
