According to Yahoo Sports, the Orioles are shopping Miguel Tejada:

Despite what they're saying publicly, the Baltimore Orioles are indeed listening to offers for shortstop Miguel Tejada, according to the Baltimore Sun. The Los Angeles Angels, Los Angeles Dodgers, Houston Astros, Detroit Tigers and Texas Rangers are among the teams that have shown the most interest, but the Angels remain the frontrunner due to their wealth of prospects. The price tag for Tejada remains unchanged: a quality big-league pitcher and two above-average players or prospects.

Now, here's what I propose:

Zito and Kendall (and/or Crosby) to Baltimore for Ramon and Miggy back.  Now, I'll admit that the nostalgic part of me wants to replay some of the glory days when we actually made it to a postseason, but I think this trade has a lot of merit.  Let's look at reasons for us to make the trade and then reasons for the Orioles to make the trade.

Reasons we should make the trade:

1.  We get a WHOLE LOT of offense by upgrading our SS and Catcher positions.  Crosby certainly hasn't been producing very much this year.  And Kendall has only hit the ball out of the park once in his tenure with us.  
2.  Our defense certainly doesn't go own at all -- Miggy and Ramon are some of the best players at their positions.
3.  Zito is probably gone after this year anyway.  Let the Orioles deal with Boras.  
4.  We can afford this deal.  Kendall's huge contract sort of "cancels out" the huge amounts of money the O's are paying Tejada and Ramon.  In fact, our payroll would actually go own by about $3,000,000.  
5.  We keep the Angels and Ranges from getting their hands on Miggy.

1.  They badly need starting pitching.  They've got enough cash to probably re-sign Zito after this year.
2.  A one year rental of Zito is a lot more affordable than most of what's out there.
3.  There's just not a lot else available in the starting pitching market.
