Basecamp, Mobile and Mobile Project Management

Here's a good rant from the NYTimes that asks more questions than it answers, titled "When the Browser Doesn't Cut it: Basecamp's Lack of Mobility." LINK

Any other suggested solutions to the lack of a mobile feature in 37Signals Basecamp? My current favorite toy, RTMilk (LINK) isn't anything as collaborative as Basecamp but it does have a fabulous BlackBerry (and iPhone) sync feature.
