Get Sandy to understand multiple chained requests about the same event.

I'd like to see the ability to apply reminders at the granular level. By this, I mean that I would like to be able to put in the following:

Sandy, Remind me that The Rock Show gig is on Thursday at 7pm. @email(1 week) @sms(1 day, 2 hours)

I'd like something like the above to result in the following:
A calendar appointment "The Rock Show gig" scheduled for Thursday at 7:00pm.
An email reminder sent 1 week in advance.
An SMS reminder sent 1 day in advance.
An SMS reminder sent 2 hours in advance.

It would be nice to be able to enter it in a more natural way, such as with the "via" and "also" keywords:

Sandy, Remind me that The Rock Show gig is on Thursday at 7pm. Also remind me via email 3 days before to call Jim about it. Also remind me about it via sms.

The preferred behavior of the above would be:
- The keyword "Also" would trigger the statement that follows to be part of a chain of commands.
- In the chained commands, the keyword "about it" would always be treated as a reference to the primary event ("The Rock Show gig", in this example).
- This keyword would be able to be placed anywhere in each sentence.
- The keyword "via" would take the next word and simply tag it with that word (so via email would be the same as @email, etc.)
- A calendar appointment "The Rock Show gig" would be scheduled for Thursday at 7:00pm with default reminders set, and with an SMS reminder set irregardless of SMS settings.
- A calendar appointment "Call Jim about The Rock Show gig scheduled for 11/27/2009 at 7:00pm" would be scheduled to occur 3 days prior to the event (with the default reminders at the default time).
